एक वेन आरेख में (n(U)=210), (n(A)=96), (n(B)=88) और (n(\(A\cup B\)^c)=58) हैं। (n\(A\cap B\)) कितना होगा?
In a Venn diagram (n(U)=210), (n(A)=96), (n(B)=88), and (n(\(A\cup B\)^c)=58). What is (n\(A\cap B\))?
Explanation opens after your attempt
C. (32)
Concept
First (n\(A\cup B\)=210-58=152), then (n\(A\cap B\)=96+88-152=32). If the outside part is given, find the union first.
Why this answer is correct
The correct answer is C. (32). First (n\(A\cup B\)=210-58=152), then (n\(A\cap B\)=96+88-152=32). If the outside part is given, find the union first.
Exam Tip
पहले (n\(A\cup B\)=210-58=152), फिर (n\(A\cap B\)=96+88-152=32)। बाहर का भाग मिले तो पहले संघ निकालें।
